Blastocyst

Your goal in Blastocyst is to destroy the comets which you can see on the screenshot. Use arrow keys to move and SPACE to fire. Sometimes the controls are a bit hard and the ship doens't really what you want it to do, but that's something typical for space shooting games.

The big green bar shows your ship's power, which is depleted by impact on your shields and by the use of your blaster.

If you spin your ship very quickly, it can fire a devastating spray of bullets, but you must use this feature sparingly as it consumes a lot of energy. If the green bar disappears completely, the slightest impact will vapourize your ship. Blasting the smallest fragments will leave green dots behind which you can collect to recharge your ship.
